'My invention relates to improvements in furnaces adapted for the heating and the unwinding of rolls. ofwire accordingfto my said improvements, the part of the furnace chamber which is situated a ove the reel carrying the'roll, of wire to be. unwound, is upwardly extended'and will thus contain a certain number of rolls of wire which become gradually. heat-ed whilethe. roll of Wire placed on the reel is being unwound. These preliminarily treated rolls are maintained in the horizontally superposed position by means of removable spindles which are optionally cooled by a current of water and which extend from the walls of the chamber at the proper places. An aperture, closed by a cover, is provided at the upper part of the chamber for the insertion of the rolls of wire.

By withdrawing the spindles which sup-- port one of the rolls of wire, this roll can be dropped into position on the next lower level, and so on until it attains the reel,

and the wire thereon which is heated tothe proper degree is finally unwound through a lateral aperture analogous to the one above described.

The improvements forming. the subject matter of the present invention are disclosed by way of example according to the construction represented in the appended drawin 's.

Fig. 1 is a sectional elevation of the improved furnace.

Fig.2 is a cross section on the line II'II of Fig.1. p 1 I r Fig. 3 is a lengthwise section on a larger scale of one of the spindles serving to support the rolls of wire in the furnace.

In Figs. 1 and 2, 7 is the metallic reel situated at the centre'of the furnace which is heated by suitable means. The reel'comprises an external flange or base 12 adapted to receive the. roll of wire to be heated, and the wire can be unwound through the lateral conduit 19. r

The chamber 3 of thefurnace is upwardly extended as shown in Fig. 1 so as to contain the rolls of wire 13.w hich are superposed and are maintained by a plurality of removable spindles 40 which traverse the wall of the furnace through tubes 41 which are imbedded in the Wall. 7 r The top of the furnace chamberis closed by a cover t2 in such manner as to provide an aperture 43 at the side which can facilitatedby theuse of thecurved guide plate 47.

h fu nac ei g heated by he us al means, and the reel? well as the spindles be ng pr id with. the r r l sof wire, it will be observed that while the roll of wire onthe said reel is being unwound through the aperture 19, the other rolls 13 placed above it will be more or less subjected to the action of heat and hence will be, gradually heated. lVhen the roll 13 is entirely unwound, I withdraw the spindles 40 holding the roll 13 situated immediately above, so that the roll will drop upon the reel, and since this roll of wire has now become considerably heated, the unwinding operation may be commenced almost at once. a

In the meantime I again insert the spindles 40 which served to hold this roll of" I thus observed that the furnace which thus operates in a continuous manner will have an outputand an efliciency which are much superior to what can be obtained withthe known furnaces. i

To obviate the rapid deterioration of the spindles 40 which are directly exposed to the flames, the said spindles may be constructed as shown in Fig. 3 and may comprise in the interior a tube 45 providing for a water circulation, the water being supplied through the hose -16.

I claim:

1. A furnace of the character described comprising a reel construction at the bottom of the furnace for supporting a coil of r 105 wire and a plurality of supports arranged above the reel for successively supporting coils of wire in their movement toward said reel structure. 7

2.
